$color(violet)((0,3), (1,10, (2, -1), (-1,5), (-2, 7)$

To find 5 ordered pairs of $2x + y = 3$

$Let x = 0, y = 3 - 2x = 3 - 0 = 3$

$Let x = 1, y = 3 - 2x = 3 - 2 = 1$

$Let x = 2, y = 3 - 2x = 3 - 4 = -1$

$Let x = -1, y = 3 - 2x = 3 + 2 = 5$

$Let x = -2, y = 3 - 2x = 3 + 4 = 7$

Ordered pairs are

$(0,3), (1,10, (2, -1), (-1,5), (-2, 7)$
